Competing many-body interactions in systems of trapped ions
A. Bermudez, D. Porras, M. A. Martin-Delgado
We propose and theoretically analyse an experimental configuration in which lasers induce 3-spin interactions between trapped ions.By properly choosing the intensities and frequenc…
Topology induced anomalous defect production by crossing a quantum critical point
A. Bermudez, D. Patanè, L. Amico +1
We study the influence of topology on the quench dynamics of a system driven across a quantum critical point. We show how the appearance of certain edge states, which fully charact…
Chirality Quantum Phase Transition in the Dirac oscillator
A. Bermudez, M. A. Martin-Delgado, A. Luis
We study a relativistic spin-1/2 fermion subjected to a Dirac oscillator coupling and a constant magnetic field. An interplay between opposed chirality interactions culminates in t…
Non-relativistic limit in the 2+1 Dirac Oscillator: A Ramsey Interferometry Effect
A. Bermudez, M. A. Martin-Delgado, A. Luis
We study the non-relativistic limit of a paradigmatic model in Relativistic Quantum Mechanics, the two-dimensional Dirac oscillator. Remarkably, we find a novel kind of Zitterbeweg…
